How many molecules of water H20 contain2.60x1023molecules of water?
2.60x10^23 water molecules contain 2.60x10^23 molecules of water.
What is held together by a hydrogen bond?
A hydrogen bond is a type of weak chemical bond that holds together molecules or parts of molecules where hydrogen is covalently bonded to a highly electronegative atom. This bond is commonly found in water molecules, DNA strands, and proteins, which allows molecules to interact and form specific structures such as double helix in DNA or secondary structures in proteins.
How many molecules would be in 546 ml of water?
546 molecules
Why soap absorb water?
Soaps are complex combinations of molecules. On the surface of the soap there are many holes and spaces between the molecules that the water can enter. There the water molecules come in and probably penetrate many layers deep into the soap, and stay there. Thus the soap expands and becomes bigger. This happens most in pure water and then less in liquids which not like water. The reason for the difference is that inside the soap there are both "hydrophilic" (water liking) and "hydrophobic" (water hating) portions of the molecules. But importantly, the hydrophilic portions are on the outside of the molecules so water can get close to the molecules. So the more like water the liquid is, the more the water can get close to the molecules and stay with them (be absorbed into the soap). When the water has other particles dissolved in it, like iced tea, Sprite or salt water, the water molecules can't get as close to the hydrophilic portions. And of course the oil molecules are repelled by the hydrophilic portions of the soap. So the answer of why soap absorbs the water is that the water molecules penetrate the soap and stay with the hydrophilic portions of the soap molecules. This happens more when the liquid is more like water.
When electricity flows through water the water molecules split into molecules of hydrogen and oxygen gas How many oxygen O2 molecules are produced from the splitting of two molecules of water H2O?
One is produced
When electricity flows through water the water molecules split into molecules of hydrogen and oxygen gas. How many oxygen (O2) molecules are produced from the splitting of two molecules of water (H2O)?
One is produced
How many moles of water H2O contain 2.0X1022 molecules of water?
6,022140857.1023 molecules---------------------------------------------1 mole2.1022 molecules--------------------------------------------------------------x molex = 0,033 moles
How many molecules of water are produced when 3 molecules of heptane burn?
C7H16 + 1102 ------->8H2O + 7CO2 So 1 molecule of heptane produces 8 molecules of water on combustion and thus 3 molecules produces 24 molecules of water.
How many water molecules are there in H2O?
There is one water molecule in H2O
How many oxygen molecules are produced for the splitting of two molecules when electricity flows through water?
2 water molecules form one molecule of oxygen.
